Al Bld is a historic district on the edge of central Jeddah, and a hidden water leak at a warehouse here is often easier to trace if the first checks take the local setting into account. The centre of Al Bld sits at 21.4860, 39.1877, about 6.6 km from the centre of Jeddah, and it lies roughly 22 m above sea level. That low, coastal position means the technician should first look at how water moves across the site rather than assuming it drains away. Al Bld is about 0.6 km from the sea coast, so the first checks should focus on the lowest floor levels, floor drains, and any slab edges where moisture could collect and spread from the sea-facing side of the building.

The rest of the diagnosis is left to the site visit. The exact route of any pipe, the condition of joints, the state of concrete at the slab, and whether a leak is coming from supply lines, drainage, or a storage tank can only be confirmed on the ground with the building open. Technicians will decide which tests to run, in what order, and where to open the structure, based on what they find. No leak location should be assumed from a description alone, and a warehouse owner should expect that some areas will only be cleared once the first sections are inspected.

To help the technician, it is useful to have the building's layout drawings, the position of any water storage tanks and their age, and a record of when damp patches, unexplained water bills, or pressure drops first appeared. If the warehouse has a tank, the internal coating cost is typically quoted at SAR 25–65 per m², so the owner should know the tank's surface area in advance for planning. Clear access to plant rooms, roof hatches, and under-floor voids also speeds the work. Noting which areas were recently repaired or repainted tells the technician where previous evidence may be hidden.

For warehouses, work is phased around operations and stored goods.

Signs worth paying attention to

If you notice one of these signs in Al Bld, it is a good moment to talk to the team:

• A hissing or trickling sound in the wall after the taps are off
• A damp patch that slowly grows on a wall or ceiling
• A water bill higher than usual with no change in use

The most common causes

• A hot line that expands and contracts with use.
• A cracked pipe under floor tiles — we check this before anything else.
• A common cause: a corroded joint inside a wall.

Tools we use in Al Bld

The steps in order

1. Meter test: We stop all use and watch the meter to confirm whether water is actually being lost.
2. Line isolation: We close valves one line at a time to see which line loses pressure.
3. Acoustic listening: We follow the sound of water escaping under pressure and compare its strength between points.
4. Thermal imaging and moisture mapping: We map how far the wet area spreads behind paint and tiles.
5. Documentation: Readings, photos and the likely position go into a written report.
